Engineers have developed a low-temperature annealing method that maintains the structure of gold and silver when the two metals are combined in an alloy. Their discovery will prove useful in the manufacture of contact lenses, holographic optical elements and other optical components, since the new alloys reflect the full spectral range.
Researchers report the formation of matter-wave polaritons in an optical lattice, an experimental discovery that enables studies of a central quantum science and technology paradigm through direct quantum simulation using ultracold atoms.
